Specification of Letters Patent.

Application filed November 27, 1914. Serial No. 874,263.

To all to 710m it may concern Be it known that l J 0113' V. MoKnn ZIE,

a citizen of the United States, residing at- La Sallc, in the county ofLa Salle and State of Illinois, have invented certain new and usefulImprovements in r-rttachments for Sewing-Machines; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in attachments forsewing machines, and has for its principal object to provide a devicewhich may be secured to a sewing machine or the like to form a seat forthe operator.

Another object of the invention is to provide a seat which may bereadily attached to any fixed piece of furniture wherein it is requiredthat a seat be used in connection therewith.

A further object of the invention is to provide a seat which may befolded to an upright position beneath the sewing machine or otherarticle of furniture when the same is not in use.

With these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which,

Figure 1 is a side view in elevation of an attachment constructed inaccordance with this invention showing the same attached to one leg ofthe stand of the machine, Fig; 2- is a top plan view of Fig. 1 showingthe upright in section, Fig. 3 is a view showing the device in itsfolded position, Fig. 4 is an end view of the cooperating legs whichsupport the free end of the seat, and Fig. 5 is a detail view of theupper end of the pivoted supporting bar.

Referring now to the drawings by characters of reference, the numeral 1designates as an entirety the stand or sewing machine with which thisdevice is used, which comprises the usual top 2, and supporting legs 3.Each supporting leg is formed with boss 4: which is recessed as at 5,and the recess is preferably triangular as shown in the drawings. Onewall of this triangular recess extends vertically, while the other wallthereof extends at an angle of substantially forty-five degrees and thesupporting rod 6 is pivoted at the apex or" the triangular opening as at7. This supporting rod 6 is provided at its right-angle extension 8which is best illus-' trated in Fig. 5, and this extension terminates inthe upper extension 9.

A suitable transversely extending bar 10 is provided and this barcarries a U-shaped member designated generally by the numeral 11, theends of the arms of which are turned so that they lie in a planesubstantially at right angles to the longitudinal axis of the U-shapedmember. The bar 10 is apertured and arranged to receive the extension 9hereinbeforc referred to. The U-shaped bar 11 is designed to cooperatewith the U-shaped bar 12 carried by the seat 13, and these bars aresupported near the lateral edges of the seat and the bightportion oi?the U-shaped member 11 is designed to lie between the bar 12 and theseat hereinbefore referred to.

Pivotally connected as at 14: is the leg designated generally by thenumeral 15, which comprises the continuous bar 16 which is bent in theform of a U-shaped member, the free ends of the arms of which are bentangularly and then outwardly to cause said U-shaped member to hang inthe position illustrated in Fig. 3 so that the bight portion thereofwill clear the remaining part of the mechanism and thereby avoid anyinterference of the several elements.

It will be apparent from the foregoing that in use when it is desired tounfold the seat, the same is pulled outwardly so that the bar 6 swingson its pivot 7. The seat is then slid so that the U-shaped member 11travels between the seat 13 and the bar 12 so that the bight portion ofthe U-shaped member 11 rests against one terminal of the bar. The leg 15is then swung downwardly in the position illustrated in Fig. 1, and itwill be seen that a seat will be provided which will effectively supportthe user of the machine or article upon which the device is used. Shouldit be desired to fold the seat to its inoperative position, it will beapparcut that the same is slid inwardly so that the bight portion of theU-shaped member 11 travels between the bar 12 and the seat 13 to theopposite terminal, whereupon the seat will fall downwardly and uponswinging the rod 6 upon its pivot'it will be apparent that the device,will assume the vertical position illustrated in Fig. 3, and the cannysnip. w

upper terminal with the stood that such'changes Weight being on theinside, will normally tend to holdthe device against accidentalmovement. 3 r v v While in the foregoing there has been shown anddescribed the preferred embodi ment of this invention, 1t is to beunderinay be made in the combination and arrangement of parts as willfall Within the spirit and scope of the invention as defined in theappended claim.

What is claimed is:

A device of theclass described comprising the Combination With astandard, of an out- W'a'rdly extending boss formed integral With saidstandard, said boss having a recess formed therein, the recess having aninclined all and a vertical Wall, a supporting rod pivotally mounted inthe apex portion of said recess in the boss,

copies of this patent may be obtained for the upper terminal five centseach, by addressing the Washington, D. G.

of said rod having a right angular extension formed thereon, the end ofsaid extension bent upwardly, a cross bar supported in the upper end ofsaid rod, a Ushaped guide 'secured to the upper face of the bar, a seat,U-shaped brackets supported to the under surface of said seat and atspaced distance apart, said guide rod of the bar adapted to be "disposedbetween the brackets and the seat allowing the sarne to slide into ahorizontal or vertical position, and means at the rear end of said seatsupporting the same when in use or in horizontal position.

Intestimony whereof I affixmy signature 7 in presence of two Witnesses.
